Gilbert Keith Chesterton (1874-1936) was a prolific English critic and author of verse, essays, novels, and short stories. He is probably best known for his series about the priest-detective Father Brown who appeared in 50 stories. Between 1900 and 1936 Chesterton published some one hundred books.

G.K. Chesterton was born in London into a middle-class family on May 29, 1874. He studied at University College and the Slade School of Art (1893-96). Around 1893 he had gone through a crisis of skepticism and depression and during this period he experimented with the Ouija board and grew fascinated with diabolism. In 1895 Chesterton left University College without a degree and worked for the London publisher Redway, and T. Fisher Unwin (1896-1902). Chesterton later renewed his Christian faith; the courtship of his future wife, Frances Blogg, whom he married in 1901 also helped him to pull himself out of his spiritual crisis.

In 1900 appeared Greybeards At Play, Chesterton's first collection of poems. Robert Browning (1903) and Charles Dickens (1906) were literary biographies. The Napoleon Of Notting Hill (1904) was Chesterton's first novel, a political fantasy, in which London is seen as a city of hidden fairytale glitter. In The Man Who Was Thursday (1908) Chesterton depicted fin-de-siècle decadence.

In 1909 Chesterton moved with his wife to Beaconsfield, a village twenty-five miles west of London, and continued to write, lecture, and travel energetically. Between 1913 and 1914 Chesterton was a regular contributor for the Daily Herald. In 1914 he suffered a physical and nervous breakdown. After World War I Chesterton became leader of the Distributist movement and later the President of the Distributist League, promoting the idea that private property should be divided into smallest possible freeholds and then distributed throughout society..

In 1922 Chesterton was converted from Anglicanism to Roman Catholicism, and thereafter he wrote several theologically oriented works, including lives of Francis of Assisi and Thomas Aquinas. He received honorary degrees from Edinburgh, Dublin, and Notre Dame universities. Chesterton died on June 14, 1936, at his home in Beaconsfield.
